Tohaina
Kua tāruatia ki te papatopenga
\frac{20750}{323}x+z=7000
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{20750}{323}x=7000-z
Tangohia te z mai i ngā taha e rua.
\frac{\frac{20750}{323}x}{\frac{20750}{323}}=\frac{7000-z}{\frac{20750}{323}}
Whakawehea ngā taha e rua o te whārite ki te \frac{20750}{323}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{7000-z}{\frac{20750}{323}}
Mā te whakawehe ki te \frac{20750}{323} ka wetekia te whakareanga ki te \frac{20750}{323}.
x=-\frac{323z}{20750}+\frac{9044}{83}
Whakawehe 7000-z ki te \frac{20750}{323} mā te whakarea 7000-z ki te tau huripoki o \frac{20750}{323}.
\frac{20750}{323}x+z=7000
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
z=7000-\frac{20750}{323}x
Tangohia te \frac{20750}{323}x mai i ngā taha e rua.
